Is there any way to tell the difference between the early WWII unmarked 20 round magazines and the early Colt unmarked 20 round magazines? I have several minty unmarked Colt 20 rounders, and I have two 20 round magazines that are a bit down on their condition and are unmarked. All were purchased at different times. I would assume that they are WWII, however, I can see no difference between the mint Colt magazines and these aside from the finish appearing to be more of a lustre blue on the Colt mags, and more of a dull blue on the other ones. Also, what is the value of a Colt unmarked magazine vs. a WWII unmarked magazine? I'm not looking to sell either type, however, I am just curious as I seem to be able to find them in the $20-$40 range (depending on who has them). Is this a good buy or am I overpaying for them? Thanks for any help.

I think you hit on the basic differences between the early commercial "Blank" model magazine and the WWII version. The early blank type XX has a smooth bright royal blue finish and was the first production box magazine provided with the Colt Thompson. The WWII version generally has a rough dull blue finish. Now days, early Blank commercial mags in good to very good condition go for $100-150. Value of the WWII version is about the same as the marked ones. This has been my experience - Hope this helps.

If one had Doug Richardon's book on this subject you could learn a bunch more than I can share here.
It is my understanding from this book of his that the Colt mags have a gap mearsured from the edge of the mag to the holes on the side of 0.35" and the military are 0.20". I highly recommend anyone collecting Thomspon mags should own his book on the subject.

As stated the answer is in Doug's book. I would suggest anyone collecting Thompsons purchased all of his books.

The drum book from Doug is also excellent.
Can't speak to his other books but I do have both the drum and mag books.
Enjoyed them both.
